Part of my practice involves people in assisted living and nursing homes. Most of these clients suffer from some form of dementia or alzheimer's disease. I offer Reiki and gentle massage which gentles the anxiety that accompanies these conditions they also calm the spirit. Lately, I've added music which seems to temporarily reconnect these people with themselves and more melodic times.
If you have a working iPod that you're done with, you might consider donating it so it can be loaded with music and help someone reconnect.
